Loom.

SPECIFICATION forming part of Letters Patent No. 596,448, dated December 28, 1897.

Application filed June 18, 1897. Serial No. 641,270. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. Nonrnnor, of Hopedale, in thecounty of Worcester and State of Massachusetts, have invented an Im provement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In that type of loom known as the Northrop loom, wherein filling-,changing mechanism is employed to automatically transfer from a suitable feeder a fresh filling-carrier to the shuttle-such, for instance, as shown in United States Patent No. 529,940, dated November 27, 18M-the introduction of such fresh filling-carrier acts upon the filling-carrier then in the shuttle to eject it therefrom through a slot in the bottom of the shuttlebox. Heretofore the ejected filling-carrier has been guided from the shuttle toa suitable receptacle by a chute made movable to permit the free movement of the picker-stick.

In my present invention I have provided a chute of peculiar construction which is rigidly secured to the lay, thereby obviating the necessary devices heretofore used to give sufficient movement to the chute to Withdraw it from the path of the picker-stick, thus greatly simplifying the construction and reducing the number of parts.

Figure 1,in front elevation, shows one end of the lay with the shuttle-box omitted, with my present invention applied to the lay. Fig. 2 is a transverse sectional view thereof on the line no, Fig. 1, the picker check-strap being omitted. Fig. 3 is a right-hand end view of the parts shown in Fig. l, and Fig. 4. is a perspective view of the chute-support detached.

The lay L, the race-plate L', longitudinally slotted at a for the picker-stick l? and for the ejection of a lling-carrier from the shuttle, and the picker check-strap P are and may be of usual construction. Beneath the slotted portion of the race-plate the lay is Acut away at LX, and within the lower part thereof the chute-support is secured, said support being preferably a bar-like casting b, slightly offset at its outer end at b and at its inner end having a downwardly and outwardly inclined arm b2. The support is attached to the lay by suitable bolts 5 and 7, the latter passing through a boss d on a bracket dx, secured to the back of the lay, said bolt 7 passing through the arm b2, which is recessed at b3, Fig. l, to receive the bolt-head..

Referring to Fig. 2 it will be seen that there is a considerable distance between the casting b and the adjacent part of the lay-beam, forming a slot for the picker-stick, a cushion m of leather or other suitable material interposed between the casting and lay-beam and through which the bolt 7 passes serving not only to position the inner end of the chutesupport b, but also to act as a cushion for the picker-stick on its inward throw.

The bolt 5 holds the offset-carb' of the support firmly against a lug L2, forming a part of the end of the race-plate L.

The guide-chute G is attached to the arm b2 of the chute-support by suitable bolts 2 2, and it is shaped at its inner end at C to extend upward close to the slot a in the raceplate, just beyond the end of the inward stroke of the picker-stick, thereby avoiding and permitting the full stroke of the latter, while affording a convenient guide for the ejected filling-carrier CX, (see dotted lines, Fig. 1,) the extended outer end of the chute affording a large guide-surface for the ejected filling-carrier.

A projection h4, extended frontward from the chute-support b, receives the usual pickercheck-strap guide f, secured in place by a suitable bolt 3, the loop-like check-strap P' being attached to a depending leg f', secured to the lay, Fig. 3. The strap passes around the picker-stick, and the front side of the strap is shown as passed behind the guide f and in frontof a second guide, shown as a depending leg b5 on the casting b. These guides act frictionally on the strap to retard its movement caused by the swing of the picker-stick- Having fully described my invention, what I claim, and desire to secure by Letters Patent, is`

l. In a loom, the lay slotted longitudinally for the ejection therethrough of a filling-car.- rier from the shuttle, the picker-stick movable in the slot, and a guide-chute for the fill- IOO ing-carrier, rigidly supported on the la'y below the slot and having an upwardly-extended portion beyond and crossing the inner end of the path of the picker-stick, substantially as described.

2. In a loom, the longitudinally-slotted lay to permit the passage therethrough of an ejected lling-carrier from the shuttle, a chute-support rigidly attached to and offset from the lay belowsaid slot, an inclined guidechute secured to said support, and a cushion for the picker-stick held between the support and the adjacent portion of the lay, substantially as described.

3. In a loom, the lay, a lling guide-chute for an ejected filling-carrier, a support for said chute, rigidly attached to the lay, at the front of the picker-stick path, and an integral and a detachable friction-guide for the picker check-strap, carried by said support, substantially as described.

4. In a loom, a longitudinally-slotted lay,

the picker-stick movable in the slot thereof, v
